Note: Using a power supply with a different voltage than the one included with the DWL-7200AP will cause damage and void the warranty for this product. If any of the above items are missing, please contact your reseller. System Requirements For Configuration:

 Computer with Windows, Macintosh, or Linux-based operating system with an installed Ethernet adapter

Internet Explorer or Netscape Navigator version 6.0 or above, with JavaScript enabled At least 128MB of memory and a 500MHz processor 3 Introduction At up to fifteen times the speed of previous wireless devices (up to 108Mbps in Super AG mode), you can work faster and more efficiently, increasing productivity. With the DWL-7200AP, bandwidth-intensive applications like graphics or multimedia will benefit significantly because large files are able to move across the network quickly. Inclusion of all three standards (802.11g; 802.11a; 802.11b) means that the DWL-7200AP is versatile enough to allow connection to almost any 802.11 network or device. The DWL-7200AP has the newest, strongest and most advanced security features available today. When used with other 802.11 WPA (Wi-Fi Protected Access) compatible products in a network with a RADIUS server, the security features include:

WPA: Wi-Fi Protected Access which authorizes and identifies users based on a secret key that changes automatically at regular intervals. WPA uses TKIP (Temporal Key Integrity Protocol) to change the temporal key every 10,000 packets (a packet is a kind of message transmitted over a network.) This ensures much greater security than the standard WEP security. (By contrast, the previous WEP encryption implementations required the keys to be changed manually.) For home users that will not incorporate a RADIUS server in their network, the security for the DWL-7200AP, used in conjunction with other WPA-compatible 802.11 products, will still be much stronger than ever before. Utilizing the Pre-Shared Key mode of WPA, the DWL-7200AP will obtain a new security key every time it connects to the 802.11 network. You only need to input your encryption information once in the configuration menu. No longer will you have to manually input a new WEP key frequently to ensure security. With the DWL-7200AP, you will automatically receive a new key every time you connect, vastly increasing the safety of your communication. 4 Features

Strictly adhering to the IEEE standard, the D-Link AirPremierTM AG wireless family of products will allow you to securely access the data you want, when and where you want it. You will be able to enjoy the freedom that wireless networking delivers. A wireless local area network (WLAN) is a cellular computer network that transmits and receives data with radio signals instead of wires. Wireless LANs are used increasingly in both home and office environments, and public areas such as airports, coffee shops and universities. Innovative ways to utilize WLAN technology are helping people to work and communicate more efficiently. Increased mobility and the absence of cabling and other fixed infrastructure have proven to be beneficial for many users. Wireless users can use the same applications they use on a wired network. Wireless adapter cards used on laptop and desktop systems support the same protocols as Ethernet adapter cards. People use wireless LAN technology for many different purposes:

Mobility - Productivity increases when people have access to data in any location within the operating range of the WLAN. Management decisions based on real-time information can significantly improve worker efficiency. Low Implementation Costs - WLANs are easy to set up, manage, change and relocate. Networks that frequently change can benefit from WLANs ease of implementation. WLANs can operate in locations where installation of wiring may be impractical. Installation and Network Expansion - Installing a WLAN system can be fast and easy and can eliminate the need to pull cable through walls and ceilings. Wireless technology allows the network to go where wires cannot go - even outside the home or office. Inexpensive Solution - Wireless network devices are as competitively priced as conventional Ethernet network devices. Scalability - WLANs can be configured in a variety of ways to meet the needs of specific applications and installations. Configurations are easily changed and range from Peer-to-Peer networks suitable for a small number of users to larger infrastructure networks to accommodate hundreds or thousands of users, depending on the number of wireless devices deployed. 6 Wireless Basics (continued) Standards-Based Technology The DWL-7200AP Wireless Access Point utilizes the 802.11a, 802.11b and draft 802.11g standard. The IEEE 802.11g standard is an extension of the 802.11b standard. It increases the data rate up to 54Mbps (108Mbps in Super G mode) within the 2.4GHz band. The 802.11a standard also increases the data rate up to 54Mbps, but within the 5GHz band. Both 802.11a and 802.11g utilize OFDM technology. This means that in most environments, within the specified range of this device, you will be able to transfer large files quickly or even watch a movie in MPEG format over your network without noticeable delays. This technology works by transmitting high-speed digital data over a radio wave utilizing OFDM (Orthogonal Frequency Division Multiplexing) technology. OFDM works by splitting the radio signal into multiple smaller sub-signals that are then transmitted simultaneously at different frequencies to the receiver. OFDM reduces the amount of crosstalk (interference) in signal transmissions. The DWL-7200AP offers the most advanced network security features available today, including WPA. In addition to its compatibility with 802.11g and 802.11a devices, the DWL-7200AP is compatible with 802.11b devices. This means that if you have an existing 802.11b network, or a network with a mixture of 802.11g, 802.11a and 802.11b, the devices in that network will be compatible with the DWL-7200AP. 7 Wireless Basics (continued) Installation Considerations Desktop and laptop computers with wireless network adapters installed can access the D-Link AirPremierTM AG DWL-7200AP from virtually anywhere within its operating range. Keep in mind, however, that the number, thickness and location of walls, ceilings, or other objects that the wireless signals must pass through, may limit the range. Typical ranges vary depending on the types of materials and background RF (radio frequency) noise in your home or business. The key to maximizing wireless range is to follow these basic guidelines:

1 2 3 4 Keep the number of walls and ceilings between the DWL-7200AP and other network devices to a minimum - each wall or ceiling can reduce your D-Link wireless products range from 3-90 feet (1-30 meters.) Position your devices so that the number of walls or ceilings is minimized. Be aware of the direct line between network devices. A wall that is 1.5 feet thick (.5 meters), at a 45-degree angle appears to be almost 3 feet

(1 meter) thick. At a 2-degree angle it looks over 42 feet (14 meters) thick! Position devices so that the signal will travel straight through a wall or ceiling (instead of at an angle) for better reception. Building materials can impede the wireless signal - a solid metal door or aluminum studs may have a negative effect on range. Try to position wireless devices and computers with wireless adapters so that the signal passes through drywall or open doorways and not other materials. Keep your product away (at least 3-6 feet or 1-2 meters) from electrical devices or appliances that may generate extreme RF noise. 8 Getting Started Right out of the box, with its default settings, the DWL-7200AP will automati-

cally connect with other D-Link AirPremierTM AG products. IP ADDRESS Note: If you are using a DHCP-capable router in your network you will not need to assign a static IP address. If you need to assign IP addresses to the computers on the network, please remember that the IP address for each computer must be in the same IP address range as all the computers in the network, and the subnet mask must be exactly the same for all the computers in the network. For example: If the first computer is assigned an IP address of 192.168.0.2 with a subnet mask of 255.255.255.0, then the second computer can be assigned an IP address of 192.168.0.3 with a subnet mask of 255.255.255.0, etc. IMPORTANT: If computers or other devices are assigned the same IP address, one or more of the devices may not be visible on the network. An Infrastructure wireless network contains an access point or router. The Infrastructure Network example, shown on the following page, contains the following D-Link network devices:

To check the IP address assigned to the wireless adapter, double-click on the local area connection icon in the taskbar > select the support tab and the IP address will be displayed. (Please refer to Checking the IP Address in the Networking Basics section of this manual.) If it is necessary to assign a static IP address to the wireless adapter, please refer to the appropriate section in Networking Basics. If you are entering a DNS server address you must also enter the default gateway address. (Remember that if you have a DHCP-capable router, you will not need to assign a static IP address. See Networking Basics: Assigning a Static IP Address.) 39 Troubleshooting (continued) 3. Check that the drivers for the network adapters are installed properly. You may be using different network adapters than those illustrated here, but this procedure will remain the same, regardless of the type of network adapters you are using.

tion?

D-Link products let you access your network from virtually anywhere you want. However, the positioning of the products within your environment will affect the wireless range. Please refer to Installation Considerations in the Wireless Basics section of this manual for further information about the most advantageous placement of your D-Link wireless products. 5. Why does my wireless connection keep dropping?

Antenna orientation- Try different antenna orientations for the DWL-7200AP. Try to keep the antenna at least 6 inches away from the wall or other objects.

If you are using 2.4GHz cordless phones, X-10 equipment or other home secu-

rity systems, ceiling fans, and lights, your wireless connection will degrade dra-

matically or drop altogether. Try changing the channel on your access point and wireless adapter to a different channel to avoid interference.

Keep your product away (at least 3-6 feet) from electrical devices that generate RF noise, like microwaves, monitors, electric motors, etc. 6. Why cant I get a wireless connection?

To establish a wireless connection, while enabling Encryption on the DWL-7200AP, you must also enable encryption on the wireless client.

For 802.11a, the Encryption settings are: 64-, 128- or 152-bit. Make sure that the encryption bit level is the same on the access point and the wireless client.

For 802.11b, the Encryption settings are: 64-, 128-, or 256-bit. Make sure that the encryption bit level is the same on the access point and the wireless client. Make sure that the SSID on the access point and the wireless client are exactly the same. If they are not, wireless connection will not be established. Please note that there are two separate SSIDs for 802.11a and 802.11b. The default SSID for both 802.11a and 802.11b is default. 42 Troubleshooting (continued) 7. Resetting the DWL-7200AP to Factory Default Settings After you have tried other methods for troubleshooting your network, you may choose to Reset the DWL-7200AP to the factory default settings. To hard-reset the D-Link DWL-7200AP to factory default settings, please do the following:

Locate the Reset button on the back of the DWL-7200AP

Use a paper clip to press the Reset button

Hold for about 10 seconds and then release

After the DWL-7200AP reboots (this may take a few minutes) it will be reset to the factory default settings 43 Technical Specifications Standards
